Explanation / Answer

guage pressure P = 4*gamma / r

gamma = 0.0375 cm

a) r = 1.85 cm

P = 4*0.0375/1.85x10^-2 = 8.108 N/m^2

b) r = 3.95 cm

P = 4*0.0375 / 3.95x10^-2 = 3.797 N/m^2

c) when they merge

V = V1 + V2

V = 4/3*pi*r1^3 + 4/3*pi*r2^3 = 4/3*pi*R^3

R^3 = [0.0185^3 + 0.0395^3]

R = 0.0408 m

P = 4*gamma / r

P = 4*0.0375/0.0408

P = 3.6756 N/m^2
